Re: cooling problems ,b100

there is a pee hole, it's on the left hand side of the engine, facing forward, just behind the carb. have you checked the water pump impeller? also, when checking the impeller, check the sealing ring that goes in the top of the water pump housing, it seals the discharge tube to the housing, and i've had that one happen as well.
